version: '3.2'
# p.g.o consists nominally of:
# A service to sync the tree to $TREE_DIR && update the index.
# The index updater simply submits work items into sidekiq.
# ElasticSearch to managed updates and serve documents.
# SideKiq requires redis.
#
# To this end we define 4 containers.
#  - HTTP Serving: Serves the site, and the /sidekiq endpoing.
#  - Elasticsearch: runs the elasticsearch service.
#  - Redis: Run Redis for Sidekiq.
#  - Refresher: Syncs the package tree and pushes updates into sidekiq.
#
# For further information about usage during development / production
# please refer to docker-compose.override.yml
